    This paper proposes the idea of a “small volume” in which to consider complicated processes to create structures in phase transitions of first and second order in the foundry. The small volume is chosen based on the classical theory of crystallization and its use for quantum mechanics. A numerical solution of Stefan-Schwarz’s task was presented by obtaining the temperature field of solidification of a composite cast in a squeeze casting. This little volume we proposed for a good possibility in the direction for a theoretical possibility of hybridization of production and technology.

    The identification of the heat exchange intensity at the work surface of the mold is defined by the base information of the type and movement of the solidification front. Parameters and their influence are shown on the type and movement of the solidification front: initial melt temperature; initial temperature of the mold; the ceramic coating on the work surface of the mold; distribution of the mass of the mold. The methodological link of these parameters is shown in the creation of each casting technology.
